In 1939, Alfred Lion and Francis Wolff, two young émigrés from Berlin, founded the legendary jazz label Blue Note Records in New York. The label dedicated itself exclusively to the recording of American jazz music. Blue Note Records discovered and produced an impressive roster of jazz stars including Miles Davis, Herbie Hancock, John Coltrane, Sonny Rollins, Wayne Shorter, Thelonious Monk and Quincy Jones. It Must Schwing! tells the moving story of two friends united by a love for jazz, and of their profound belief in equality and freedom.
